SAFE-DOOR.

Speccaton of Letters Patent.

Patented May 14, 190'?.v

Application filed 'July 3.1906. serial No. 324,648.

To all whom t may concern:

Be it known that I, EDWARD PAsooE, a citizen ofthe United States,` residing at Sioux City, in the county of Woodbury and State of Iowa, have invented new and useful Imrovements in Safe-Doors, of which the folowing is a speciiication. j

invention relates to safe doors, the object of the invention being to rovide means oors of safes, whereby the same are rendered more secure and effective against burglars, aneffective interlocked engagement being obtained between the door and the body of the safe inde pendent of the ordinary looking means.

With the above general object in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and 2o claimed.

2 5 door open in edge view. Fig. 3 is a front elevation of the safe, showing the door thrown all the way open and illustrating the 'manner of mounting the door. Fig. .4 is a sectional plan view, showing the mechanism for im- 3o parting a partial rotary movement to the door. Fig. 5 is a vertical sectional view oi' a portion of said mechanism. Fig. 6 is a detail elevation of the worm, showing the reversible ratchet.

Referring to the drawings, 1 designates a safe of any desired size and general construction, 2 representing the front wall of the safe, the same being provided with the doorway or opening 3, the said opening being preferably 4o round, while 4 desi nates the doorwhich is also round and beve ed on its outer periphery or rim and adapted to fit snugly into the doorway or opening 3 in the manner illustrated in Fig. 1. n

In carrying out the present invention, the door 4 is centrally journaled and adapted to turn on a center bolt or pin 5 which is carried by a hinged door supporting arm 6, the latter being bifurcated and the branches thereof 5o being hinged at 7 to the body of the safe, as

shown in Figs. 1 and 3. It is to be under stood that the door 4 is journaled directly on the bolt or pin 5 and that the latter is carried by the projecting end or portion of the hinged 55 arm 6.

ery or rim with mutilated or interrupted of the doorway fit into the unthreaded spaces 9 of the door'.

Under the preferred embodiment of this invention, the threaded segments on the door and in the doorway are of equal length circumferentially of the opening and the length of the intervening spaces 9 and 11 are also of a length equal to the length of the threaded segments. and partially turned on the axis bolt or pin 5, the threaded segments of the door and doorway are moved into engagement with each other and in such turning of the door, said threaded segments interlock and crowd the doorinward with a tight fit into the door opening. The door is also shouldered to receivc agasket 12 which iinds a seat or bearing against a corresponding shoulder 13 in the doorway, thus giving a practically airtight and lire-tight fit.

The mechanism for imparting a partial revolution to the door 4 embodies a worm segment 14 secured to the door and having the teeth 15 thereof projecting slightly beyond the periphery of the door, as shown in Figs. 1, 3 and 4. Meshing with the segment 14 is a worm 16 which is journaled on a vertical aXis and mounted on the front of the safe by means of a bracket 17 secured rigidly to the safe. The worm 16 is journaled at its upper end in said bracket and also carries a ratchet wheel 18 fast thereon, which Therefore, when the door isshut otally mounted on thel shorter arm 20 of a hand-lever 21 which is fulcrumed at 22 on the elbow 23 of a fulcrum pin 24 which eX- tends downward through the projecting portion of the bracket 17 through the ratchet wheel 18 into the worm 16, as clearly shown in Fig. 5, the fulcrum pin 24 being loose in the wheel 18 and worm 16. Thedog 19 is double-ended or provided with two engag- IIO lIO

ing points as shown in Fig. 6 and also with a projecting shank 25 which extends upward and is engaged by a spring 26 also carried by the short arm 2() of the lever 21, said spring acting on the shank of the dog to hold either engaging point thereof in engagement with the teeth of the ratchet wheel 18, according to the direction in which it is desired to turn the worm and revolve the safe door.

After the door has been closed by means of the ordinary handle 27, the handle 21 is raised from the vertical position indicated by dotted lines in Fig. 5 to the horizontal po siton indicated by full lines in the same iigure, and the dog 19 having been set at the proper angle, the lever 21 is swung horizontally, whereupon thedog 19 engages the ratchet wheel 18 and turns the worm 1 6 which in turn engages the worm'segment 14 and turns the door on its pvot 5 far enough to move the threaded segments of the door into interlocked engagement with the threaded segments in the doorway. The safe door may then be locked by means of any type of lock usually eme ployed.

In order to open the safe door, after the same has been unlocked, the operation just above described for bringing the door to its seat, is reversed, thereby moving the thread- .ed segments of the door and doorway out of engagement with each other, after which the door may be thrown open by grasping the handle 27 and moving said door outward on the hinges 7. The axis of the worm 16 is in 'direct alinement with the hinges 7 so that the worm segment 14 remains in engagement with the worm at all times, whether the door is open or closed.

I claim:

1. The combination with a safe having a circular doorway, of a circular door, a hinged arm carrying a pivot on which the door is directly journaled at its center, interlocking means on the door and within the doorway movable into and out of engagement by a partial rotation of the door, and means for partially rotating the door c mprisi ng a worm segment carried by the door, a worm mounted on the safe, a hand-lever, and ratchet mechanism associated with said hand-lever and worm, substantially as described.

2. The combination with a safe having a circular doorway, of a circular door, a hinged. arm mounted on the sale and carrying a pin or pivot on which the door is directly lioni'- naled at its center, interlocking means on the door and within the doorway adapted to be thrown into and out of engagemei'it by a partial rotation of the door, and means for partially rotating the door comprising a worm segment on the door, a worm mounted. on the safe, a ratchet wheel on said worm, a handlever, and a reversible dog carried by said hand-lever and cooperating with the ratchet wheel, substantially as described.

3. The combination with a sale having a circular doorway, of a circular door iitting the same, a hinged arm connected to the sa'le and carrying a pivot on which said door is directly ournaled at its center, interlocking means on the door and within the doorway movable into and out ol engagement by a partial rotation of the door, and. means for partially rotating the door comprising a worm segment carried by the door, a worm mounted on the safe, a ratchet wheel connected with said worm, a l'ulcrum pin l'or said worm having an angular extension, a hand-lever fulcrumed on said extension, and a dog carried by said hand-lever and movable into and out of engagement with the ratchet wheel and adapted to turn the worin in either direction.

In testimony whereof I allix my signature in presence of two witnesses.

EDWARD Pascoli.
